AI translates the explanation and quiz text while preserving code and answer scoring.

Binary data is handled with `ArrayBuffer` and typed views (`Uint8Array`, `DataView`). The Streams API (`ReadableStream`, `TransformStream`) processes large payloads chunk-by-chunk.

js
const buffer = new ArrayBuffer(16);
const view = new DataView(buffer);
view.setUint32(0, 42, false); // big-endian
